Ask a Capetonian about the Southern Suburbs and they will picture oak-lined avenues, the mountain looming over Newlands and the rain that rolls in off it in winter.

Stored product pests around Southern Suburbs
Damp pantries are a magnet for stored product moths and flour beetles in family homes. Restaurants, delis and wine estate kitchens need regular checks of dry stores.
The housing spans Victorian semis in Rondebosch and Claremont, big Edwardian and mid-century family homes in Newlands and Bishopscourt, student digs near UCT, blocks of flats around Wynberg and Claremont, and old farm-style homesteads and estates in Constantia.
Something most people miss
Many people throw out the rice and keep the open bag of pasta next to it. Weevils happily breed in pasta too, so check everything made from grain.
Sealed containers protect your other food from weevils, but they also contain an infestation if you buy a bad bag, so you only lose that one container.
What gives them away
Tick every sign you have noticed. It takes ten seconds.
Why it matters: Weevils are not known to bite or carry disease, but they ruin food, and the larvae inside the grain mean you cannot simply sieve them out. Infested stock has to be thrown away, which is a real cost for bakeries, restaurants, food distributors and farms with stored maize. In bulk storage, weevil activity creates heat and moisture pockets that encourage mould and further spoilage. For food businesses, weevils found by a customer or an auditor can damage trust very quickly.
How we handle weevil control in Southern Suburbs
Weevils develop inside the grain, so no surface spray can reach them while they are still in the kernel; removing infested food is the main treatment. We inspect every grain, pulse and cereal product, separate what is infested, and bag it for disposal. Shelves, cupboards and the gaps around them are vacuumed and cleaned, and we apply a targeted crack and crevice treatment where weevils are sheltering, keeping it well away from open food. For commercial stores and farm silos with heavy infestations of bulk grain, fumigation may be the only practical option, and we plan that as a separate job. Pheromone or food-baited traps are then used to check that numbers have dropped.

Stopping a repeat visit
- Check dried beans and lentils for small round holes before putting them in the cupboard.
- On farms and smallholdings, clean out silos and bins completely before refilling with new harvest.
- Freeze new bags of rice or flour for three or four days before you store them if weevils have been a problem before.
- Store rice, maize meal and samp in airtight glass or thick plastic containers, because weevils chew through thin plastic bags and cardboard.
- Use older stock first and avoid topping up a container with new grain on top of old.
How much will it cost?
For a home, the price mostly depends on how many cupboards are involved and whether the weevils have spread into other rooms. For businesses and farms, the volume of stored grain, how it is stored and whether fumigation is needed are the big factors. We quote for free, and food businesses with ongoing risk often prefer a contract with regular monitoring.
Weevils breed much faster in warm conditions, so infestations that began unnoticed in winter usually show up between November and March. A rice weevil can go from egg to adult in about a month in summer heat, compared with several months in a cold Cape winter. Warm, humid pantries can keep them active all year.
Questions we get asked in Southern Suburbs
Can you treat weevils in a silo or warehouse?
Yes. Larger stores may need fumigation or regular monitoring, and we will inspect and quote for the right approach.
How did weevils get into my sealed bag of rice?
The eggs were most likely already inside the grains when you bought it. Female weevils lay eggs inside individual kernels, so the bag can look perfect from the outside.
Are the weevils in my beans the same as in my rice?
No. Bean weevils are seed beetles that only attack pulses, while rice and maize weevils attack grain, but the clean-out and storage advice is much the same.
Do you come out to Southern Suburbs for weevil control?
Yes. Southern Suburbs is part of our regular Southern Suburbs route, along with Rondebosch, Claremont, Newlands, Wynberg. Most bookings are done within about 48 hours, and after-hours visits can be arranged.
Can I eat rice that had weevils in it?
It is not known to be harmful, but the grain is contaminated with insects and droppings, and we would throw it away.
Will weevils spread to the rest of the house?
Adults wander, so you may see them on walls and counters, but they only breed where there is grain or seed. Clearing the food source stops them.
